Osmosis describes the movement of water across a biological membrane and down its concentration gradient. In chemiosmosis, usefu
l energy is harnessed by the cell from the movement of _______________ across the inner mitochondrial membrane into the matrix _________________ a concentration gradient. A)ATP, against
B)protons, down
C)electrons, down
D)ADP, against
Chemiosmosis is the diffusion of ions through a selective permeable membrane. It specifically refers to the production of ATP through the movement of hydrogen ions through an inner membrane during cellular respiration. Hydrogen ions diffuse from an area of high proton concentration to one of lower concentration.
